Some Applications of Microwave Energy
When we speak of microwave, what first comes into our minds are fast, hot meals. The reality is that there are many more applications of microwaves aside from what we know and is used in industries for heating, drying, and processing.
If you have a microwave oven, then you know what microwave energy is. When heating materials, microwave systems use high-frequency electromagnetic radiation, and it is also used for industrial RF components and systems. There are certain frequency bands where industrial microwave heating systems operate for industrial applications in the country. This will help prevent interference with other frequency bands.
Microwave heating is used to process many materials. In commercial food products, microwave energy is the main component of thermal processing used to eliminate bacterially. Drying grain and removing moisture from the wood for use as lumber uses microwave energy. Moisture from different powdered substances in the pharmaceutical industry are removed using microwave energy. In order to coat rubber and plastic materials with different types of coatings, microwave energy is used.
When microwave is used in industries, the cost of microwave heating or drying processes is minimized by power consumption and material processing. An an example would be microwave heating systems developed that uses only a small percentage of energy required by other heating systems per liter of water evaporated from the processed material, with reduced thermal processing time.
This heating system is designed like a tunnel, and materials pass through this tunnel where the materials are exposed to microwave radiation all the way for the purpose of heating and drying. The result of passing through the tunnel is uniform heating of materials with minimal thermal processing times.
This microwave heating system is a tunnel-like structure. You can use these microwave systems for drying and sterilization. It can process both solid and liquid foods which preserving the essential nutrients within the food and preserve its appearance and flavor. This system is considered environmentally friendly because they don’t produce exhaust gases and it efficiently uses electrical energy.
For materials samples, a microwave heating system is designed with a continuous conveyor belt that runs through the tunnel. Microwave energy is applied to the tunnel from a high -power source, using high-power rotating antennas to achieve even heating of material samples.
Microwave heating systems are also built for pasteurization and food-processing applications. And there are also those developed for waste treatment and biotechnology research laboratories. You can expect increased shelf life for fruits and vegetables with microwave heating systems. Materials are efficiently heated in a smooth production flow in industrials applications of microwave heating systems.
Moisture content of raw materials can be reduced with microwave drying systems for industrial applications. This is applied to the automated drying of fruits, vegetables, meat, and fish, and even to the production of cereals such as corn flakes.
